Answer:
V = 1/3×pi×r^2×h
V= 1/3 × 3.14 × 20×20 × 38 = 15,909.333333333 = 15909
i am not sure about calculation ,so check it again yourself please .
Well we set up the equation for a direct variation
<span>y=kx</span>
Lets take a point... (-8, -6)
Plug that in
<span>−6=k(−8)</span><span>
And solve for 'k' to get *indeed* 3/4</span>
Answer:
3
Step-by-step explanation:
Convert the percentage into a decimal:
Set up a proportion using the hours Andrea worked, and the percentage compared to Carmen's workload:
The numerator will represent the hours worked, and the denominator will represent the percentage when compared to Carmen's workload.
Cross multiply the fractions:
Divide both sides by 0.45 to get x by itself:
Carmen worked
20.56 hours last week.
Answer:
x = 17
Step-by-step explanation:
For the parallelogram to be a rhombus then then the diagonal must bisect the given angle, thus
3x - 11 = x + 23 ( subtract x from both sides )
2x - 11 = 23 ( add 1 to both sides )
2x = 34 ( divide both sides by 2 )
x = 17
